Abstract
Systems and methods for operating a hoist and hook assembly may method comprising determining a clutch slip via a clutch sensor, determining an overload via a load sensor, and cutting a cable coupled to the hoist and hook assembly in response to the clutch slip determination and the overload determination.
Claims25
A method of operating a hoist and hook assembly, comprising:
- determining, by a controller, a clutch slip via a clutch sensor;
- determining, by the controller, an overload via a load sensor;
- determining a duration of at least one of the clutch slip or the sensed overload is at or above a first predefined threshold;
- and
- cutting, by the controller, a cable coupled to the hoist and hook assembly in response to the clutch slip determination and the overload determination.
A non-transitory, tangible computer readable storage medium having instructions stored thereon that, in response to execution by a processor, cause the processor to perform operations comprising:
- determining, by the processor, a clutch slip using a clutch sensor;
- determining, by the processor, an overload using a load sensor;
- determining a duration of at least one of the clutch slip or the sensed overload is at or above a first predefined threshold;
- and
- cutting, by the processor, a cable coupled to the hoist and hook assembly using a cable cut cartridge in response to the clutch slip determination and the overload determination.
A hoist system comprising,
- an airframe mechanically coupled to a hoist assembly;
- a cable disposed between the hoist assembly and a hook assembly;
- a clutch sensor coupled to the hoist assembly;
- a load sensor coupled to the cable;
- and
- a controller configured to:
- determine a clutch slip via the clutch sensor;
- determine an overload via the load sensor;
- determine a duration of the clutch slip is at or above a first predefined threshold and a duration of the sensed overload is at or above a second predefined threshold;
- and
- cut the cable via a cable cut cartridge in response to the clutch slip determination and the overload determination.
A method of operating a hoist and hook assembly, comprising:
- determining, by a controller, a first clutch slip via a first clutch sensor on a motor side of a gear train of the hoist and hook assembly;
- determining, by the controller, an overload via a load sensor;
- and
- cutting, by the controller, a cable coupled to the hoist and hook assembly in response to the clutch slip determination and the overload determination.
A method of operating a hoist and hook assembly, comprising:
- determining, by a controller, a clutch slip via a clutch sensor;
- determining, by the controller, an overload via a load sensor;
- initiating, by the controller, a cable cut in response to determining the clutch slip and the overload;
- and
- cutting a cable coupled to the hoist and hook assembly in response to the clutch slip determination and the overload determination.
A method of operating a hoist and hook assembly, comprising:
- determining, by a controller, a clutch slip via a clutch sensor;
- determining, by the controller, an overload via a load sensor;
- indicating aurally or visually that a predefined threshold has elapsed;
- and
- cutting, by the controller, a cable coupled to the hoist and hook assembly in response to the clutch slip determination and the overload determination.
